PAPER-FASTENING MACHINE.

Application filed December 31, 1912.

To all whom it may concern:

Be it ,known that I, GEORGE H. PEMBROKE, a citizen of the United States,residing at New Brunswick, MiddleseX county, in the State of New Jersey,have invented certain new .and useful Improvements in Paper- FasteningMachines, of which the following s a full, clear, and eXactspecification.

My invention relates to improvements 1n means for fastening and bindingtogether sheets of paper or. analogous articles by means of an eyelet,and the same has for its object more particularly toprovide a simple,eflicient and reliable apparatus which is com pact in form, simple andpositive in operationand not liable to get out of order.

Further said invention has for its object to provide a machine for thepurposes specified which is designed to receive a series of fasteningmembers mounted upon a suitable support, and then feed the same, onebyone, to the driving mechanism whereby .the sald fasteners are causedto secure the paper together.

Further said invention has for its object to provide a machine in whichthe fastener in position tobe driven will remain properly in suchposition until it is actually driven, and will not feed another fastenerinto operative position until the first fastener has been actuallydriven into the paper or otherwise disposed of.

Further said invention has for its object to provide a machine for thepurposes specified which shall be compact in form, simple inconstruction and so arranged that access may be had to the interiorthereof for the purpose of adjustment and cleaning.

To the attainment of .the aforesaid objects and ends my inventionconsists in the novel details ,of construction, and in the combination,connection and arrangement of parts hereinafter more fully described andthen pointed out in theclaims.

eyelets in position thereon, Fig. 7 is a detail perspective vlew showlngthe construction of the lower ends of thechuck jaws.

In said drawings 10 designates the ma chlne as a whole comprising a base11 from which projects a standard 12. 13 denotes a cylindrical sectionwhich is rigidly secured to thestandard or upright 12 by screws 13 13Vithin the easing 131s secured a head 11 having a flange 15 thereonresting upon the upper edge of the casing 13. The head 14 is providedwith a circular opening having its inner lower portion beveled at 16.

17 denotes a thumb screw which extends through the upper end of theupright or standard 12 and engages the ,inclosed portion of the head 14whereby to secure said head firmly in position within the top of thecasing 13 and maintain the operating parts within said casing duly inposition therein.

18 denotes asha-ft which is disposed within the opening in the head 141. The said shaft 18 is provided at its upper end with an operatinghead 19, and at its lower end with a reduced portion 20.

21 denotes a longitudinal groove provided in the shaft 1S,through whichextends a pin 22 having its inner end secured to a tubular section :23slidably mounted within the shaft 18. I i

The head 1 1 is provided .at its forward portion with a vertical recess24 in the base of which is vertically secured an adjusting screw 25whose upperendserves as a support for the forward end of the pin 22carriedloy the tubular section 23, and to limit the downward vmovementofsaid tubular section within the shaft 18.-

2,6 denotes a yoke secured in the upper side of the head 14whichemhraees the pin 22 and serves to limit the upward movement of thetubular section 23 when the shaft 18 and head 19 are drawn upwardly.

27 denotes a support which is substantially circular in outline andsecured to the lower end by means of a screw 27. The said support 27 isprovided at its opposite sides with vertical recesses 28, 28 withinwhich are vertically disposed jaws 29, 29 which are pivotally mountedupon pins 30, 30 carried by said support. The upper ends of said jaws29, 29 are beveled in order to engage with the beveled surface 16 of thehead 14, and the lower ends of said jaws 29 are arranged atsubstantially right angles to the vertical portions thereof and havetheir opposing edges recessed to form a socket for an eyelet, and also apassage for the rod or support for the eyelets.

31 denotes an annular member or carrier disposed within the lower end ofthe casing 13 and provided at its opposite sides with pins 32, 32 whichextend through recesses 33, 33 provided in the casing 13. Upon the outeropposite sides of the casing 13 are secured guide plates 34, 34, andupon the outer sides of the casing 13 but within said guide plates 34,34 are secured pins 35, 35.

36, 36 denote springs secured at their upper ends to the pins 35, 35arranged upon the outer side of the casing 13, and at their lower endsto the pins 32, 32 secured to the annular member or carrier 31.

The annular member 31 has its inner surface rounded at 37 to act as acam when the rounded portions of the jaws 29, 29 are brought intocontact therewith and serves to cause the ends of said jaws to be guidedinto engagement with each other and to embrace the eyelets and the rodtherefor.

The base 11 is provided at its center with a socket into which is fittedan anvil 38 having an upwardly projecting pin or stud 39 and anannularly grooved base 40 surrounding said pin or stud 39 which servesto turn the lower edge of an eyelet outwardly when the eyelet is forcedthereon by means ofthe jaws 29, 29.

The operation of the apparatus is as follows: The eyelets for use inconnection with the machine are mounted upon a rod 41 which is providedat its upper end with a ring or finger portion 42 adapted to rest uponthe upper end of the tubular section 23 in order to prevent the lowerend of said rod coming in contact with the pin or stud 39. The said rod41 is of such diameter that the tubular portions 43 of the eyelets willslide freely thereon while the lower end of the rod 41 is provided witha slight bur or head of such size as to be just sufficient to preventthe tubular portion of the eyelets 43 passing freely thereover. By thismeans the lowermost eyelet upon the rod 41 will be held duly in positionupon the said rod ready for driving.

In order to drive an eyelet, the shaft 18 must first be drawn upwardlyby means of its head 19 until the pin 22 on the tubular section 23within said shaft 18 engages the yoke 26 and prevents further movementof said shaft 18 and tubular section 23. At the same time the upperbeveled ends of the jaws 29 will be brought into contact with the innerbeveled edge 16 of the head 14, and cause the lower ends of the jaws tobecome separated and assume the position indicated at Fig. 4. As soon asthe lower ends of the jaws 29 have become thus separated the rod 41,with the eyelets thereon, will be permitted to drop sufficiently toallow the lowermost of said eyelets to be brought into position directlybelow the lower edges of the horizontal portions of the jaws 29, 29whereupon said jaws are caused to be brought together with thesucceeding downward movement of the shaft 18, and con nected parts dueparticularly to the en gagement of the rounded portions of the jaws 29,29 with the inner rounded surface of the annular member 31. WVith thismovement of the shaft 18, and the parts carried thereon, the apparatuswill be in the position indicated at Fig. 2.

In order to drive the fastener into the paper or other article to bejoined together it simply becomes necessary to strike upon the surfaceof the head 19 a sharp blow with the hand and thereby cause the shaft 18and its reduced portion 20 together with the support 27 to be drivendownwardly and the annular member 31 to be carried downwardly at thesame time in opposition to the tension of the supporting springs 36, 36.

As soon as the lower edge of the tubular portion of the eyelet strikesthe grooved base 40 of the anvil 38 the lower edge of said tubularportion will be flared outwardly and the eyelet caused to clench thepaper or material between the flange 43 of said eyelet and the newlyformed flange at the lower edge thereof.

Should the machine for any reason fail to rivet the eyelet with thefirst impact the parts will be caused to resume the position indicatedat Fig. 2, that is to say, the lowermost eyelet on the rod 41 willremain in position below the horizontal portions of the jaws 29, 29 andprevent the feeding of the succeeding one. The shaft 18 and partscarried thereon may thereupon be forced downwardly again by a sharp blowwith the hand upon the upper surface of the head 19, and the eyeletriveted.

In order to bring the succeeding eyelet in position for driving it isfirst necessary to raise the shaft 18 by means of its head 19, as firstabove described, to separate the lower ends of the jaws to permit theentire stack of eyelets upon the rod 41 and said rod to drop therequired distance.
